Description

Induction Plastic Hot Water Boiler with Multiple Heating Structure {Multiplex Heating type Induction Plastic Hot Water Boiler}

When a high frequency current passes through an induction coil formed by twisting a plurality of thin coils into a disk shape or an elliptic plate shape, a heating plate formed on the front and rear surfaces of the induction coil causes an eddy current due to an electromagnetic induction phenomenon. Hot water boiler of direct heating type with high heat efficiency composed of Induction Heater type that generates Joule heat (heat generated by resistance).

In addition, it is configured to contact the insulated gate bipolar transistor in which high heat is generated when the high frequency is produced and the inflow pipe where cold water flows, so that a separate cooling means for cooling the hot insulated gate bipolar transistor is unnecessary.

Water introduced into the inlet pipe is primarily heated by the heat generated from the insulated gate bipolar transistor.

Induction coil number (x) consisting of a heating process in which the first heated water is heated secondly by a heating plate formed on the front side of the induction coil, and the second heated water is heated thirdly by another heating plate formed on the rear surface of the induction coil (x). Induction plastic hot water with multi-heating structure that makes the boiler's manufacturing process simple and the boiler's own weight is simple because multi-heating structure that heats once more (2x + 1 time) twice as much as Boiler.

The conventional hot water boiler is an indirect heating type hot water boiler that heats a container (piping, hot water container, or cover of a heating element) by generating heat from an oil, gas, electricity, etc. as an energy source to heat the water contained in the container. .

Oil and gas boilers that generate heat by burning fossil fuels have many problems such as additional costs, harmful substances generated during combustion, and low thermal efficiency due to the storage and supply of fuel.

In addition, the conventional electric boiler has the advantage of easy installation and operation compared to the oil or gas boiler, but indirect heating method to heat the container surrounding the heating element to produce heat to heat the water in contact with the container, low thermal efficiency wide Not suitable for zone heating due to the high price of electricity,

Existing boilers are made of steel, and the manufacturing process of the boiler is a major factor to increase the manufacturing cost of the boiler by manual labor such as welding work. Therefore, it is unable to supply hot water boilers with low cost and thermal efficiency to consumers.

The low thermal efficiency, which is a disadvantage of the conventional electric boiler, is solved by a high thermal efficiency heating method,

Insulated Gate Bipolar Transistor (IGBT), a semiconductor device capable of high-speed high-speed switching as an essential element for the induction heater method, is a separate device that cools the insulated gate bipolar transistor even when high heat is generated during high frequency production. To cool the insulated gate bipolar transistor without cooling means,

In the boiler manufacturing process of a multiple heating structure in which the water introduced into the inlet pipe is heated a plurality of times (7 times) until it flows out of the outlet pipe, the welding process is simplified and the generation of harmful substances can be minimized. Hot water boiler with multiple heating structure to lighten the boiler's own weight.

When the high-frequency current produced by the insulated gate bipolar transistor passes through an induction coil formed by twisting a plurality of thin coils into a disc or elliptic plate, electromagnetic induction occurs on the heating plates formed on the front and back of the induction coil. Joule heat (heat amount generated by resistance) is generated by eddy current (swirl current).

The heating plate composed of such an induction heater method becomes a heating element that generates heat, and thus the hot water boiler of the direct heating type with high efficiency is constructed by directly heating the water.

In addition, a separate cooling means is required to cool the insulated gate bipolar transistor by cooling the insulated gate bipolar transistor by configuring the insulated gate bipolar transistor in which high heat is generated when the high frequency is produced, and the inflow pipe where cold water is introduced. Do not

Primary heat is applied to the cold water flowing into the inlet pipe with heat generated from the insulated gate bipolar transistor,

The heating plate is formed on the front and the back of the induction coil, respectively, so that it is heated twice as many times (6 times) as the number of induction coils (3 times) and heated multiple times (7 times). The induction plastic hot water boiler is composed of a multi-heated structure, which is molded into plastic, so that the manufacturing process of the boiler is simple and the boiler's own load is light.

Induction hot water boiler according to the present invention can minimize the power consumption by direct heating method with high thermal efficiency,

In high frequency production, the heat generated from the insulated gate bipolar transistor is used to heat the cold water flowing into the inlet pipe firstly, and a heating plate is formed on the front and the back of the induction coil to double the number of induction coils (3) (6 times). By heating more than) you can maximize the efficiency of the boiler.

In addition, there is no need for a separate means to cool the insulated gate bipolar transistor heated during high frequency production, and the heating part that produces heat, which is the core part of the hot water boiler, is molded of plastic, thus minimizing welding work in the manufacturing process of the boiler. And it is possible to minimize the manufacturing cost of the boiler has the effect that it is possible to supply a hot water boiler that is easy to use and good thermal efficiency to the consumer at a low price.
